Introduction
Pilot was quick to react to the limited success of the expensive C-600MW, and released a cheaper Capless less than one year after the previous model. The price was initially halved, and soon afterwards it was further reduced to JPY 2000. It is questionable whether these pens were different models or not. Their nib units are perfectly compatible.

Nib unit
Type II. In 14 K gold. There are three variations, labeled as IIa, IIb and IIc, with the same dimensions and perfectly interchangeable. These labels do not reflect possible changes in the color of the feeds--either black or transparent. IIa unit is usually associated to models C-300SW and C-300GW, and model C-200SW can be seen with both IIb and IIc types. However, it is very likely that there existed exceptions to this rule.
Pic IV
Type IIa, usually associated to model C-300SW and C-300GW.
Pic V
Type IIb, seen on model C-200SW.
Pic VI
Type IIc, usually associated to model C-200SW.
Pic VII
The differences among the three types of nib units are on the nibs. From top to bottom, types IIc, IIb, and IIa.
Additional information
These pens were made in a very wide number of colors. In fact, Pilot is not aware of how many variations were released.
